I'd love to try out that system .
I generally have no problem backing trailers by steering with hand on the bottom of the steering wheel moving the direction I want the trailer to go. But this Ford system uses the cameras to help show where the trailer will end up and has follow-up counter-steer. Looks like it has very interesting potential
In spite of the rather arrogant follow-up posts in that link, I've seen plenty of people who claim they are experts mess up impressively from time to time especially when tired after a trip , at night , or, say, backing a short utility trailer when used to a long boat trailer.
Why knock it if they have not tried it?
